Please make sure that Immerse is receiving the game audio output properly. A good way to do this is to look at the Sound Wheel. You should see the dots in the Sound Wheel light up and pulsate. If they are not lighting up, then please check the ‘Audio Device’ configuration in your game and make sure that ‘Speakers (Immerse for Logitech)’ is selected as the audio output device in the game. Once set, you will hear the volume change take effect.
For games such as CS: GO, please do the following:
Go to Game Settings → Audio Settings
You must unselect and select ‘Speakers(Immerse for Logitech)’ in the ‘Audio Device’ dropdown.
Note: This manual reselection process is needed for CS: GO to output game audio to Immerse.
